Ni gute ushobora guhitamo crane ikwiriye y'icyuma cy'icyuma? Ibintu by'ingenzi n'amabwiriza afatika

Mu musaruro w'uruganda rw'ibyuma, cranes zikora nka "amaboko y'ibyuma," zikora ibikorwa by'ibanze nko gufata ibikoresho fatizo (raw materials), gutwara billet, no kuzamura ibicuruzwa byarangiye. Imikorere yabo igira ingaruka ku buryo butaziguye imikorere y'umusaruro, ibipimo by'umutekano, n'ikiguzi cy'imikorere. Ariko, ibidukikije bikabije by'inganda z'ibyuma - birangwa n'ubushyuhe bwinshi, umukungugu uremereye, hamwe n'imitwaro iremereye - ishyira ibisabwa byinshi cyane ku guhuza kwa cranes. Ni gute ushobora guhitamo crane ikwiriye y'uruganda rw'icyuma? Iki gice kigaragaza ibipimo by'ingenzi byo guhitamo hashingiwe ku bisabwa by'ibanze kugira ngo bigufashe gufata icyemezo gikwiye.

Inganda z'ibyuma zifite ibintu bigoye kandi bitandukanye by'imikorere, hamwe n'itandukaniro rikomeye mubisabwa bya crane mu byiciro bitandukanye. Kurugero, niba ikoreshwa mugutwara kontineri z'ibyuma byashongeshejwe mu ruganda rukora ibyuma, crane igomba kuba ifite ubushobozi bwo gutwara imizigo iremereye kandi ihangana n'imirasire y'ubushyuhe burenze 1,500 °C. If used for handling coiled materials in the cold rolling workshop, the focus should be on smooth lifting and positioning accuracy to prevent surface damage to the coiled materials.

Cranes mu bubiko bw'ibikoresho fatizo zigomba gufata imizigo yo gupakira no gupakira amabuye y'agaciro menshi na coke, bityo ni byiza gushyira imbere cranes nini za gantry zifite imigozi irwanya kwambara hamwe n'amapine arwanya gusenyuka. In contrast, cranes in rolling mills must often maneuver in narrow spaces, making bridge cranes more suitable, provided they feature compact structural designs and flexible control systems. Kugenzura neza imikorere ya sisitemu yo kubara ibaruramari ni intambwe ya mbere yo guhitamo ibicuruzwa bikwiye.

Kwibanda ku mikorere y'ibanze: Ibimenyetso bitatu by'ingenzi byerekana ko ibikoresho bikwiriye

Load capacity: The rated lifting capacity must be determined based on the maximum lifting weight, while also considering dynamic load impacts. Kurugero, mugihe cyo kuzamura ibyuma, ubushobozi bwo kuzamura bwa crane bugomba kuba hejuru ya 20% ugereranije nuburemere nyabwo kugirango habeho umurongo wumutekano; If multiple hooks are used in coordinated operations, the synchronization precision of each hook must also be considered.

Kurwanya kubangamira ibidukikije: Ahantu hashyushye cyane, moteri za crane n'insinga zigomba kuba zikozwe mu bikoresho birwanya ubushyuhe kandi zifite sisitemu yo gukonjesha ku gahato; Mu bice by'ivumbi, amasanduku ya moteri afunze na moteri zirinda umukungugu zigomba gutorwa kugira ngo hirindwe imyanda guteza ibibazo by'imiyoborere myiza; Ahantu hatoshye cyangwa kwangiza (nko gukaraba acide), imiterere y'icyuma igomba kuvurwa hakurikijwe ruswa, kandi ibice by'ingenzi bigomba gukorwa mu cyuma kitagira ingeso.

Umutekano w'imikorere: Umuvuduko wo kuzamura n'umuvuduko w'ingendo bigomba guhuza n'umuvuduko w'umusaruro, hamwe no kugenzura imikorere yizewe ya feri. Kurugero, mugihe cyo gufata ibyuma byashongeshejwe, uburyo bwo kuzamura bugomba kuba bufite sisitemu ya braking ebyiri kugirango habeho guhagarara byihutirwa mugihe kitunguranye; Mu buryo bwo guteranya buhanitse, ikosa ryo guhagarara kwa crane rigomba kugenzurwa muri ±5mm.

Inganda z'ibyuma ni inganda zifite ibyago byinshi, kandi imikorere y'umutekano wa crane ntishobora kubangamirwa. Ibicuruzwa bigomba kwemezwa n'ikigo cy'igihugu gishinzwe kugenzura ibikoresho byihariye kandi byujuje ibisabwa byihariye kuri cranes z'ibyuma muri "Amabwiriza y'umutekano wa Cranes" (GB6067), nko gushiraho ubwirinzi bw'ingendo zirenze urugero, imipaka irengeje urugero, hamwe na buto zo guhagarara byihutirwa.

Kuri cranes zikoreshwa mu kuzamura ibyuma byashongeshejwe, kubahiriza "Technical Conditions for Metallurgical Cranes" (JB / T7688) nabyo birakenewe. Ibi bikubiyemo gukoresha ibyuma birwanya ubushyuhe bwinshi mubyubwubatsi, no gufata igishushanyo mbonera hamwe na moteri ebyiri hamwe na reducers ebyiri kugirango habeho guhagarara neza nubwo igice kimwe cyananiwe. Byongeye kandi, sisitemu yamashanyarazi ya crane igomba kuba ifite ubudahangarwa bwo kubangamira kugirango hirindwe imikorere mibi mubidukikije bikomeye bya elegitoroniki.

IMVAHONSHYA - Ibiciro by'ingengo y'imari y'igihe kirekire birenze ibiciro by'ibicuruzwa

Amasosiyete menshi agwa mu mutego wo kwibanda gusa ku giciro cya mbere cyo kugura mugihe cyo guhitamo, birengagiza ibiciro byo kubungabunga n'ibiciro by'ingufu mu gihe cy'igihe kirekire. Nubwo igiciro cy'ibicuruzwa gishobora kugabanuka bitewe n'ibiciro by'ibicuruzwa

Kuramba: Ibice byubwubatsi bikozwe mubyuma bikomeye, bifite ubuzima bwa serivisi bwimyaka irenga 20, bigabanya inshuro zo gusimbuza 50% ugereranije nibikoresho bikozwe mucyuma gisanzwe;

Ingufu z'ingufu: Cranes zifite moteri zihindagurika hamwe n'ibishushanyo byoroheje bigabanya ikoreshwa ry'ingufu ku kigero cya 30% ugereranije n'ibikoresho bisanzwe, bigatuma bikwiriye by'umwihariko ibikorwa bikurikiraho 24/7 mu nganda z'ibyuma;

Byoroshye kubungabunga: Igishushanyo mbonera cya crane ya modular kigabanya igihe cyo kubungabunga, nkibice bya moteri byihuse bishobora kugabanya igihe cyo kuruhuka kuva kuminsi 3 kugeza amasaha 8.

Ukoresheje kubara neza ibiciro byo kugura, kubungabunga no kubungabunga ibidukikije, urashobora guhitamo ibikoresho bifite igiciro nyacyo.

Selection process: A comprehensive methodology from assessment to verification

Ubushakashatsi bw'ibisabwa: Gukorana n'amashami y'umusaruro, ibikoresho, n'umutekano kugira ngo umenye ibisabwa byo kuzamura mu byiciro byose, gukora "Crane Operation Parameter Table" kugirango asobanure amakuru y'ingenzi nk'ubushobozi bwo kuzamura, icyiciro cy'akazi, n'umuvuduko wo gukora;

Guhitamo abacuruzi: Gushyira imbere ibicuruzwa bifite ubunararibonye mu nganda z'ibyuma, nka Henan Mining, inzobere mu mashini ziremereye. Ubuhanga bwabo bwa tekiniki mu nzego zo hejuru nk'ingufu za nucléaire n'ibyuma bihuza neza n'ibisabwa bikomeye by'inganda z'ibyuma;

Kwipimisha ku rubuga: Gusaba inganda gutanga ibice by'icyitegererezo cyo kugerageza, kwigana ubushyuhe bwo hejuru, imizigo iremereye, n'ibidukikije by'ivumbi kugira ngo barebe ko ibikoresho bihagaze neza n'imikorere y'umutekano;

Nyuma yo kugurisha: Hitamo inganda zifite ubushobozi bwo gutanga igisubizo cyihuse, kugenzura gutunganya ahantu mu masaha 24 mugihe habaye ikibazo cyibikoresho, hamwe no gusuzuma ubushobozi bwo gutanga ibice kugirango wirinde igihe kirekire cyo kuruhuka kubera gutinda kwibice.

Guhitamo cranes z'inganda z'ibyuma bisaba uburinganire bwuzuye bw'ibipimo bya tekiniki, ibisabwa mu mikorere, hamwe n'ibikorwa by'igihe kirekire. Gusa mu kwibanda ku mikorere y'ibanze, kubahiriza ibipimo by'umutekano, no gushyira imbere ibidukikije byihariye by'imikorere umuntu ashobora guhitamo crane ijyanye n'umusaruro kandi ihendutse—"umufatanyabikorwa w'ibyuma" nyakuri. Muri iki gihe cy'irushanwa rigenda rirushaho kwiyongera, crane ikora neza kandi yizewe ntabwo ari igikoresho cy'umusaruro gusa ahubwo ni umutungo w'ingenzi mu kuzamura irushanwa ry'isosiyete.
